PTV VISWALK AND VISSIM ARE FULLY INTEGRATED

Pedestrians, motorized traffic, cycles and public transport can be

simulated together.

At crossings pedestrians obey traffic lights, at non-signalized crossings

either pedestrians or vehicles can be given priority.

Pedestrians can alight from trains and board trains.

Key Benefits of using PTV Viswalk | 2013


What is pedestrian engineering?

It is the discipline that focuses on the most prevalent

mode of transport – walking

VISWALK

Viswalk is used to

plan for pedestrians

(inside and outside stations

and buildings)

evaluate planning alternatives

plan operations

simulate evacuations

determine travel times

create 3D-simulations


WHAT IS PEDESTRIAN MICRO-SIMULATION?

The accurate simulated representation of people walking -

every step

Simulation of the interaction of pedestrians in crowds

Simulation of the interaction between pedestrians and the built

environment

The accurate simulation of the interaction between pedestrians and

private or public modes

of transport


THE SOCIAL FORCE MODEL

PTV’s Pedestrian Simulation software has been

developed based upon the Social Force Model (SFM)

originally introduced in 1995 by Prof. Helbing.

The SFM is now well accepted amongst the transport

planning and academic communities.

The force on a pedestrian is calculated at any time from

the influences of their desire, other pedestrians and the

built environment such as walls or buildings.

Driving force in the

desired direction of

motion

Forces from borders

Forces from

fellow

pedestrians

Driving force in the

desired direction of

motion

Forces from borders

Forces from

fellow

THE SOCIAL FORCE MODEL

PTV Enhancements

PTV enhancded the Social Force Model with additional functionality to

enable modelling:

Movement through multi-storey buildings,

Crossing streets (with or without regulation)

Board and alight from trains,

Queue in elaborate queuing systems,

Bi-directional movement through extended narrow corridors


VISWALK USES

Interchange between modes of

Transport

Rail and Metro

Buses

Taxi

Walking

Cycling

Private car


VISWALK USES

Traffic and Streets

Signal Timings

Interaction with traffic (cars, buses, freight and cycles)

Public Transport boarding and alighting


VISWALK USES

Stations

Boarding, Alighting, Platforms, Escalators, Ticket Gates etc


VISWALK USES

Stadiums

Operations, ticket turnstiles, stairs, evacuation, retail placement,

links to public transport


VISWALK USES

Buildings

Access

Internal Layout

Stairs, lifts

Evacuation


Network modelling – large scale, national, regional and local

transport network developments and demand modelling
